4 ELrALEXANDER,-citizens ofthe United States,

Beit known that we,'l`HonA-s J BAKER and residingat Findlay, fin the county of Hancock and vState of Ohio, have inventednew and useful Improvements -inFlue-Cleaners, of which lthefollovving is a specification.y -i' Our invention relates to an improvement in flue-cleaners, and moreparticularly to that class o f flue-cleaners in which a blast of steam or a1r is used ,to create-a vacuumA to suck-out the dirt and soot'fromthe flue. C

, The object of our invention is to provide-an 'bodiment of our `inventionis shown and where in like numerals oflreference refer 'to'similar .parts in the several-views, Figure l is a perA spective view of our improved flue-cleaner. Fig. 2 isa longitudinal section 'of the same,

A improved Hue-cleanerof this type,which can easily be manipulatedbyan attendant to clean .all ofthe tubes ina boiler of any type. f

In the drawings, wherein a preferable ,em-

andFigB is a detail view showing the manner of securing the'handle to the cleaner.

Referring now more particularly to the drawings, A indicates the body pf our cleaner,

'which is in the form ofa hollow elbow-pro"- viled at one end with the nozzle A", which is adaptedto be inserted in the flue to be cleaned, and at the other end with the nozzle A2, eX-

tendinjg at substantially right angles to thel nozzle A,' which-forms an outlet for the soot and dirt from the ilue. An annular ilange A3 is formed around the end of the nozzle A. This flange A3 abuts against the end of the boiler and forms a tight joint therewith to prevent the escape of any sootfrom the tube whenthe nozzle A is inserted therein'. In practice We prefer to make the nozzle Al quite small and the flange A3 quite Wide, so that the cleaner may be used' withequal facility on boilers provided with large and small tubes.

B and-B' are two steam or air nozzles secured in the curved portionv of the elbowshaped body A. disposed that they are in alinement with the nozzle A2; so that a jet of steam or air coming therefrom'would pass directly through said nozzle A2 and create a strong suction through the nozzle A and the boiler-tube. The nozzle The nozzles lB and B are so smal in. 166,565.. No modelar- 'fis-Secured` atthe topmost portioriko'f the curved part of theel bow-shaped bodyA, -vvhile accumulate in thebend ofpthe elbow around the. base of` the steamor-a'irnozzle; Wehave overcome thisdiiculty'by placing aplurality :ent heights on` the curved portion` of th-'e- :el-y bow. A channel or pipe connectsthe n'ozzles B and B with7 a steam onairinlet- 'which isadapted to be connected by a 'flexible-tub- .pipe b is an approximately circularshapedfear C, provided at `its center with an?y aperture, c and having one of its sides formed with radial has secured upon oneendja ferrule, which cleaner.

` ,Gr is a bolt adapted to pass through the apertures c and f in the ears C and' F, and H is 'a thumb-nut adapted to screw on the end of the bolt G to clamp the ears Eand F together. It will be seen from the above description that by loosening the thumb-nut H lthe handle D can be adjusted to any desired angle relative to the body A ofthe cleaner and that when the thumb-nut H .is tightened the corrugated portions on the ears C and F engage with each other andhold the 'handle securely in its adjusted position.
